Cold Email Infrastructure Setup That Protects Your Main Domain
We set up the domains, mailboxes, authentication and sending tools your cold email program needs, so you can scale outreach safely from day one.
The problem
The challenges holding your B2B growth back.
You do not have safe, scalable infrastructure for cold email. Your team is unsure how to set it up without damaging your domain. Outbound should never put your core business email at risk.
Sending from the main domain
Cold email from your company domain puts everyday email at risk.
Technical setup is unfamiliar
DNS records, mailbox providers and warm-up are new territory for most teams.
Infrastructure that does not scale
A few mailboxes cannot support the volume your targets require.
Overview
Our Cold Email Infrastructure Setup services.
Built for B2B teams launching cold email or rebuilding outreach after deliverability problems.
Cold email infrastructure is the technical foundation of outbound: secondary domains, mailboxes, DNS authentication, warm-up and the sending platform. Getting it right is the first step in any B2B cold email program.
Our infrastructure setup service plans how many domains and mailboxes you need for your volume, registers and configures them, sets up SPF, DKIM and DMARC, connects mailboxes to your sending tool and starts warm-up. Domains redirect to your main website so prospects who check them find you.
Everything is created in accounts you own and documented so your team understands the setup.
Cold Email Infrastructure Setup is part of our Cold email service.

Usually a few weeks before mailboxes are ready for full campaign volume.
